CLASSIC CORE

Classic Core® is the industry’s leading name in combination (“combi”) core panel construction where cross bands of thin MDF are utilized in place of veneer cross bands in an otherwise domestic veneer core panel construction. This combination of MDF and veneer core provides a smoother, improved surface over softwood veneer core cross bands, reducing core telegraphing potential through the decorative wood face and back. Classic Core constructions are also lighter in weight and superior screw holding over composite cores of equivalent thickness. These smooth combination panels are ideal for applications including furniture, cabinetry and fixtures.

Classic Core can be manufactured with either ULEF MDF cross bands (which contain added formaldehyde) or with polymeric diphenylmethane diisocyanate (pMDI) bonded crossbands which do not contain added formaldehyde, and are sold by Columbia under the PureBond® brand. PureBond Classic Core® may contribute to LEED® 2009 credit IEQ 4.4 and conforms to CARB II exempt emission requirements called for in LEED V4.What Lies Beneath Makes A Difference

Classic Core provides a smooth, sound surface with higher density than traditional veneer core. This reduces the potential for core telegraphing through decorative veneer overlays. Classic Core also significantly reduces finishing problems stemming from allowed open knot holes or open joints in standard veneer core constructions.
